Compared with cucumbers, peppers, and other crops, the output of tomatoes is relatively large. Therefore, tomatoes have become more popular as greenhouse vegetable greenhouses, especially greenhouse vegetable greenhouses and widely used in agricultural production. Tomatoes are grown in greenhouses in Shandong. However, we all know that after all, greenhouses have limited space. For tomatoes, pruning can be a very complicated task. It is based on the rational use of space resources and the consideration of sunlight. Pay attention to the location of tomatoes and other issues. Junxian County, Gansu Agriculture will explain the eight points of attention in the operation of cherry tomatoes in greenhouses in Shandong.
1. Rational fertilization and water application: When adopting continuous dry pruning on one hand, it is necessary to ensure adequate fertilizer and water, and attention must be paid to the retention and cultivation of the upper lateral branch.
2. Pay attention to the row spacing of tomatoes: The greenhouses in winter in sunlight greenhouses and winter and spring are often planted with common single stem pruning, that is, early-maturing varieties are highly dense and leave one fruit per plant; middle and late-maturing varieties are planted at about 667 square meters, about 2500, and each plant stays 4- 6 ear fruit, 2-3 results per panicle;

3. Prevent pests and diseases: Tomatoes in the greenhouse in the pruning, the plants with symptoms of the virus should be carried out alone to avoid the spread of human disease;
4. The tomato above ground has a mutually promoting relationship with the root system. Premature pruning will affect root growth. Therefore, the fork should not be too early. When the fork is crossed, it is required not to leave piles, and it is not possible to bring out too much skin on the spindle. To reduce the wound surface as much as possible, generally do not use tools such as scissors, because the scissors are easy to spread the virus;
5. To repair tomatoes: The use of continuous pruning should be performed as soon as possible. Early, small wounds, easy to heal;
6. In greenhouse cultivation in autumn and winter, in spring cultivation of greenhouses, continuous single stem pruning and continuous picking and pruning are often used. When using these two pruning methods, we must pay attention to thinning and fruit thinning. In general, 5-10 spikes of fruit are kept in individual plants and 2 to 3 fruits are kept in each ear.
